PCIE 1X to16X Extender on hp sff

[Soufiane11]

hi guys!
please help my !!
i have a hp compaq 8000 elite sff (smal form factor).
and i just bought a gtx 650 that doesn't require 6pin or 8pin power cable (less than 70w)
but the problem is that card is not low profile so it doesn't fit in my hp case!
and im planing to buy an PCIE 1X to16X Extender Riser Card Adapter with USB 3.0 Cable!

https://www.amazon.co.uk/to16x-Extender-Riser-Adapter-Power/dp/B01MQJAQ14

but i dont know if it will work in my hp ! because this PCIE 1X to16X Extender Riser Card Adapter with USB 3.0 Cable ships with an 6 pin Power Cable, and my stock hp psu (240w) doesn't have any 6pin or 8pin power cable and i dont know if the extender will power the gpu (gtx 650) with just usb3.0 that connect to pcie x1 or not (hp compaq 8000 elite sff have 2 pcie x1 and 1 pciex16.
or that 6pin power connect that come with the extender only needed with power gpus (more than 70w) maybe??
please guys help

Don't use GTX 650 on 240W PSU. You most likely are going to kill your PC (depending on protections built into PSU).
Minimum recommended PSU for that card is 400W.

There are people use this pc with gtx 750ti that eat 75w compare to 60 to 65w

The PC actually has a PCIe x16 slot, so instead of converting a 1x to a 16x slot to run a GPU (a terrible, terrible idea) you can just get a 16x PCIE extender. (A good idea, commonly used in "thin" HTPC cases to support GPUs, and other normal cases to have vertically mounted GPUs)

Like this one: https://www.amazon.co.uk/dp/B06X43QT1D/ref=psdc_949408031_t1_B00J7LGOEO

Ahh i didn't know about that 16x extender!! but i got no way to mount the gpu because that 16x extender only flex in one way and hp sff cases are very small. but what about the PCIE 1X to16X Extender Riser Card Adapter with USB 3.0 Cable! Will it work with my asus gtx 650 Or its required a high end psu with power cables?

uhh, the 16x extender can flex both ways, and there's nothing for you to mount any gpu to with you current setup, which is also a big problem probably. You'll have to rig up some kind to keep GPU stable.

The 1x to 16x is only meant for like cryptocurrency(bitcoin) mining rigs because those don't really need all the PCIE lanes to fully use the GPU.
If you try to use a 1x to 16x extender for gaming, you're going to have a bad time.

ok! so im good with the flexible pcie x16 to x16 extender like this one :

but can it flex and turn around so i can stick it behinde my pc and put the gpu there?

 

[James Mason]

"behind" your PC? Like how?

That one isn't long enough i don't think, to like bend under your PC and mount out back, you'd need like... a 2 foot long extender for that.

You should probably just get rid of your 550 (which is old and pretty bad by todays standards) and just get a low profile GPU:

im already bought a asus gtx 650 with no power connection require i think i just try to mount it horizontally in my case and glue it or some like that!
but thanks you soo much guys for helpful information!

I just hope you don't blow up your pc by using that insufficient PSU.
That is pretty likely scenario though.

an hp compaq 8000 elite sff can barely reach 80w full load without a gpu
even if i add a gpu it wont reach its maximum load because of cpu bottleneck (core 2 duo e8400)
